Jiang Hailiu and others took the drawings created by Ling Xia and mobilized the 60,000 soldiers of the division to start construction collectively, because the people in the city had all moved away, so in order to replenish the building materials of bricks, tiles and wood, Ling Xia ordered the abandoned houses in the distance to be removed.

When the houses were removed, Ling Xia specifically instructed the soldiers to pull out the houses in the distance and keep the buildings near the main city gate, not only that, but he also ordered all the construction waste to be blocked on the inside of the city gate, leaving only a few paths that could accommodate the soldiers on foot.

Knowing that the Battle Flag Division was stationed there, they did not immediately send troops to defend the line, but began to work hard to build walls from the city, and the soldiers of the Rock Division and the Tiger Division couldn't help laughing, and even Xiang Kunlun and Nangong Xiu kept shaking their heads, lamenting that Ling Xia didn't understand war.

When Ling Xia led the Battle Flag Division to build the city gate in the main city, the Rock Division and the Tiger Division took advantage of the opportunity of no enemy sneak attack and hurriedly sent soldiers to garrison the city wall.

The two divisions and regiments deployed the soldiers of each 10,000-person team according to the defense area, transported the bows and arrows and quivers to the city wall, and set up a long snake formation along the city wall, which was the most rational state of waiting for work, and when they saw Ling Xia, everyone felt that it was a pity, thinking that Ling Xia had missed this good opportunity for defense cultivation in vain.

Ignoring the opinions of outsiders, Ling Xia still led the soldiers to rebuild the defensive area, pick up houses, select wood, pick up green bricks, transport materials, carry stones, raise the wall, extend and widen, build city holes, and replace city gates, and all the soldiers of the Battle Flag Division were busy in an orderly manner.

After 60,000 soldiers worked day and night, seven days later, a brand new main city that shocked the world was built, although it was delayed by a few days than expected, but the effect was more perfect, Ling Xia rebuilt the city walls on both sides of the main city from the previous five meters high, to ten meters high, doubled the height, looking magnificent and magnificent.

The main city wall after the reconstruction is ten meters high, the city gate is renovated and expanded twice, the whole city gate outline is rectangular, the city gate is eight meters high, six meters wide, can make the chariot enter and exit the city gate, the arrow tower, the enemy slashing tower, the lookout tower are built on the city wall respectively.

The entire city wall was rebuilt into an overall defense system, because he had seen the strength of the island cavalry, in order to resist the enemy's cavalry attack, Ling Xia specially dug many deep ditches outside the city wall, and placed a lot of tripping horse piles and thistles outside the city wall.

The newly reconstructed city wall is mainly built around the defensive fortress system, the thickness of the city wall is the same as the height, the whole body is solid, the city wall is as stable as a mountain, the top of the wall is ten meters wide for cavalry and large teams to rush to help, soldiers do not need to go down the wall, they can take turns on the city wall.

There is an arrow tower every ten meters on the city wall, each arrow tower can accommodate five archers, when encountering an enemy attack, the archer can hide in the arrow tower, bend the bow through the reserved shooting port to shoot the enemy, with the protection of the arrow tower, the archer does not have to worry about the enemy's bow and arrow counterattack.

Between every ten arrow towers, there is a slashing tower, the slashing tower protrudes on the outer edge of the city wall, and ten soldiers are stationed inside, which is specially set up to resist the enemy who climbs the city by ladder, if the enemy climbs the wall through the ladder or hook lock, the soldiers in the enemy tower will cut the hook lock or overturn the long ladder.

In addition to the arrow tower and the enemy tower, there are four very conspicuous watchtowers on the city wall, the watchtowers are built at both ends of the city gate, and the middle of the city wall, its appearance is like a chimney, about 30 meters high, and the surrounding is dense and impermeable.

At the bottom there is an entrance for soldiers, inside is a spiral staircase, there are platforms every three meters, there are ten platforms in total, and at the top of the watchtower is an attic-like building, filled with hay and copper oil, and in the middle there is a special smoke stove, which, when lit, can instantly rise smoke.

Ling Xia made four pairs of binoculars out of crystal chips, one in each watchtower, on which four soldiers were sent to take turns on duty, their task was to use the telescope to observe the enemy's situation, once they found the enemy's traces, they would use copper oil to light the hay and release the signal, as soon as the people below saw the smoke, they knew that the enemy was coming.

As for the platforms inside the lookout, they are equipped with siege crossbows, Ling Xia placed ten heavy siege crossbows from each watchtower, which are specially responsible for calling enemy generals or other important targets, if the enemy dares to come, the siege crossbow will be mixed with bows and arrows to shoot the enemy, the siege crossbow has an amazing range, plus it is condescending, and the power is naturally stronger.

Because the city gate is the only way to enter and exit the defense area, and it is also the primary target of the enemy's attack, so Ling Xia placed ten heavy siege crossbows on each side of the city gate, and according to the range of the siege crossbows, he built a watchtower in the middle of the left and right sides of the city wall, and at that time, the four watchtowers can cooperate with each other.

According to the strength of his own side, Ling Xia built two thousand arrow towers from the city wall, two hundred enemy towers, after the successful construction, he handed over the fortifications above the city wall to Huya, in addition to the 10,000 troops under Huya's command, Ling Xia also allocated him 2,000 reserves, let him send, no one is more suitable for this task than Huya's 10,000 marksmen.

When Huya led the 10,000-strong team of sharpshooters and the 2,000 reserve soldiers into the city wall, Ling Xia told him that from today on, the 10,000-strong soldiers of the sharpshooter will be stationed on the city wall for a long time, eat three meals a day on the city wall, rest in the arrow tower day and night, take turns to rest in the arrow tower, and take turns to rest when they are free, and they must all go into battle during wartime.

In addition to the city wall, Ling Xia also transformed the ground force, he used those construction waste to form a trap behind the city gate, whether it was cavalry or infantry, if you want to enter the inner city, you must pass through this waste area, because all kinds of construction waste heaps are like hills, so the cavalry can only dismount and advance on foot.

This area is almost more than a thousand meters, and after passing through here, you can enter the main street of the city behind, but Ling Xia has already arranged the Jiang Hailiu 10,000 troops and Situ Chenfeng 10,000 people in the camps on both sides, as long as the enemy enters the street, the two 10,000 teams will charge at the same time.

At this moment, Ling Xia is ordering people to connect the alleys, alleys, mezzanines, and streets of the inner city with stones and green bricks, and he wants to connect all the areas of the inner city close to the city gate to form a super huge labyrinth, Yue Qianfeng's 10,000-strong team is ambushed from the inside, and Luo Boss's 10,000-strong team is blocked outside, once the enemy enters the maze, don't think about coming out again.

After transforming the city wall into an iron barrel, Ling Xia set up the headquarters of the division behind the city gate, which is not only close to the front line, but also can be strategically rear, Ling Xia has just built the division command camp, and wolf smoke rose on the four watchtowers at the same time, seeing this, Ling Xia's heart sank, and he ordered and ordered: "The enemy is coming, prepare for battle." ”
